(A) The last ETP is the CP
(B) The first ETP is the CP
(C) The centermost ETP is the CP
(D) Any of them can be the CP

A

D

17
Q

Minimum Rescue and Fire Fighting capability of EDTO airport is:

(A) CAT IV for all suitable airports
(B) At least one suitable airport of CAT VII
(C) CAT VII for all adequate airports
(D) Same as that of the airplane

A

A

18
Q

The EDTO diversion speed chosen by the operator is chosen for a:

(A) Maximum Range
(B) Maximum Altitude capability for terrain clearance
(C) Combination of the above
(D) None correct

A

C

19
Q

An airport can be qualified as Adequate Airport provided:

(A) The airport has at least one navaid for instrument approach
(B) The airport has adequate runway length
(C) The airport has sufficient lighting, communication and emergency services
(D) The airports have all these features

A

D

Note: The airport is considered adequate for the purpose of EDTO when it satisfies the aircraft performance requirements applicable at the expected landing weight.

20
Q

An adequate airport can be termed as EDTO En-route Alternate, provided:

(A) The visibility meets EDTO requirements
(B) The cloud ceiling is above MDA/DA
(C) The crosswind prevails within the certified limits of aircraft
(D) All of the above

A

D

21
Q

If BEFORE entering EDTO segment, weather at declared en-route alternate drops below normal and there is no other EDTO en-route alternate available, the flight crew should:

(A) Inform the ATC
(B) Continue the flight
(C) Turn back to the base airport
(D) Keep circling the flight

A

C

22
Q

If EDTO approval is for 180 minutes, the minimum cargo fire suppression capability must be for:

(A) 180 minutes
(B) 180 + 30 minutes
(C) 180 +15 minutes
(D) 180 + 45 minutes

A

C

23
Q

What is the cruise speed for the Depressurization with All Engines Operating diversion scenario after descending to FL100/

(A) 0.80 M
(B) 0.83 M
(C) LRC
(D) MCT

A

C

24
Q

On which of the following factors is EDTO Dispatch Minima NOT dependent?

(A) Weather ceiling
(B) Normal visibility Minima
(C) Geographical location
(D) Approach facility configuration

A

C

25
Q

Which of the following means are used by IOCC to keep the commander informed about adverse conditions in EDTO flight?

(A) CPDLC
(B) ACARS
(C) ADS-B
(D) SATCOM

A

B & D

26
Q

Can flight crew change the flight dispatch EEP and EXP status, en-route, if they find another adequate airport? Yes or No.

A

No

27
Q

During flight planning Sector OMDB-RPLL
Adequate Airports: OOMS, OPKC, VABB, VOPB, VYYY, VTBS, VVDN

During flight, can flight crew change the EDTO status to non-EDTO due to availability of VOMM? Yes or No

A

No

Determination of whether a flight is EDTO or non-EDTO is established during the dispatch process. The en-route alternate airports nominated at dispatch define the EEP, ETP and EXP for an EDTO flight. This does not change once airborne unless a designated alternate goes below minimums prior to EDTO entry.

28
Q

During Flight Planning, Sector: RPLL-YSSY
EDTO alternates: WABB & YPDN
Adequate Airports: RPMD & YPDN
RPMD does not meet weather minima.

Can this RPLL-YSSY flight be dispatched as EDTO flight with the above conditions? Yes or No

A

Yes

The EDTO dispatch scenario is valid as there is no requirement for the adequate Airports which define the EDTO Entry and Exit Points for the route to be nominated as EDTO alternates as long as the coverage can be provided by other Airports within the EDTO portion of the flight.

29
Q

Where do we find the flight crew procedures for EDTO?

A
